Counterproof

In engraving, a counterproof is a print taken off from another just printed, which, by being passed through the press, gives a copy in reverse, and of course in the same position as that of the plate from which the first was printed, the object being to enable the engraver to inspect the state of the plate. Counterproofing was used to produce the finest quality copperplate printing; the second print consisted of delicate lines, and lacked the beveled impressions seen in the original print.
